TiffsAndAstro

noice ty i mean, they list a uk address on their website for their uk hq, there must be a reason for that. id guess. still a bit odd that Nina from their CS replied to me at like 4am this morning. must be doing the CS night shift

yeah it just confused the hell out of me. i reckon a lot of new people buy it, get it after two weeks, then buy adapters, find they don't work, repeat.

world peace and a cure for cancer. but im learning to manage my expectations.

the technical drawing of the svbony version i plonked in my post above. its more than possible i've misinterpreted it as i've never touched an astro cam in my life. it looks very similar to the one for the zwo camera on flo website. shockingly my first option would be to do to flo what i've done to svbony (see my post above) but with zwo/astro essentials equivalents, but after a quick look its a lot more expensive. better quality and support im certain, but not something i can do right now. having said that, i think after i read svbony's reply/shopping basket, there's a decent chance ill wait a bit longer and buy the zwo version and an uv/ir cut and the bits you suggest from flo. maybe i get lucky and there's a customer return. if i was harry hill there would be only one way to decide this....

so ive decided to "reach out" to svbony's "We Love Experience" program as i have an entire 1 follower on astrobin and i'm pretty certain that legally makes me an influencer just on the slight chance svbony aren't convinced, i've asked them to stick everything i need to connect the camera, rotator, filter drawer and adapters onto the back of my flattener into a shopping basket for me. and if i have to add vat and brexit taxes to it (which will be a deal breaker i think). will be interesting to see their response.

im sure i'd like it, which is why i don't want to try the free trial

so below is a diagram hopefully help explain some of my questions if anyone is so kind: ideally i'd like to retain as much as possible from stage 1 if/when i eventually move to stage 2. questions, sorry : 1 the svbony camera diagram is below. i assume the camera nose peice can be removed to gain 6mm more backspace if needed? 2 stage 1 needs an M42 to Mxy adapter of 37.5mm length to make 12.50 +37.50 = 55mm. maybe need some thin shims too if any backspace issues. what is the Mxy thread or adaptor name id need? 3 stage 2 needs a M42 filter drawer to M42 camera rotator to M42 to Mxy adapter which need to total either 37.50mm, or 43.50mm if i remove the camera nose piece? 4 flo website says a 2 inch filter fits inside the flattener nose piece (though if you look at my pics of it above it looks like it will also fit between back of the flattener and the t2 adapter?) will it also fit inside stage 2 filter draw? not high priority as uv/ir cut filters seem fairly cheap? i won't be using the nose peice so i can continue to have everything from the back of the focus tube screwed together. 5 er that's it i think? though i've probably missed something obvious links to the equipment: svbony SV705C Planetary Camera https://www.svbony.com/sv705c-color-planetary-camera-imx585/#F9198J Astro Essentials M48 adapter for Sky-Watcher Newtonians and 72ED Refractor (M54) with 10mm Backfocus https://www.firstlightoptics.com/adapters/astro-essentials-m48-adapter-for-sky-watcher-newtonians-and-72ed-refractor-m54-with-10mm-backfocus.html?_gl=1*1am6k7j*_up*MQ..*_ga*NDg0MTg5MjczLjE3MTgxMzAzMjA.*_ga_F6VGWQ0MW9*MTcxODEzMDMxOS4xLjEuMTcxODEzMDMyMy4wLjAuMA.. sw 72ed https://www.firstlightoptics.com/telescopes-in-stock/sky-watcher-evostar-72ed-ds-pro-ota.html?_gl=1*1arqiqx*_up*MQ..*_ga*NDg0MTg5MjczLjE3MTgxMzAzMjA.*_ga_F6VGWQ0MW9*MTcxODEzMDMxOS4xLjEuMTcxODEzMDMzNC4wLjAuMA..

https://www.svbony.com/sv705c-color-planetary-camera-imx585/#F9198J-W9184A Is what I'm thinking but maybe not as good a deal as I though. Free filter drawer and an ir/uv cut filter for £7 more. Rotator looks nice, if it will fit for £20 too. The svbony cs lady who emailed replied to me at 4am is called Nina. I have a feeling she'll have a colleague name Ciril. Maybe he has two PhDs? Looking at it a bit more I think I might have to not try and get everything in one go, prices aren't quite as low as I hoped. If I can attach an ir/UV cut filter without a drawer for now, I'll just get camera and that filter leave it place inside the updated optical train somewhere and hope I can fit a rotator, filter drawer and dual narrowband filter at a later date that will all magically fit together first time.

I want to get camera, filter drawer, UV/it cut filter and rotator and any adapters I need from one place. As svbony have a UK headquarters I'd hope vat is included and no Brexit taxes but I'll check with them. I'll post an amazing crayoned working drawing with dimensions/m adapter numbers and stuff here as soon as I get a chance and hope some kind soul can give me a sanity check on it as I'm bound to mess something up with this. Maybe still in time for a bit more 'zoom' on some galaxies

im managing to do multiple session combining (just about) in siril thanks to help from here. not fully manual stacking though, about 50% so far. i even redid my m101 last night waiting for clouds to not clear. its not great for many reasons, but it is data from three sessions doing a mosiac is concern and i might need to be able to do that if i get a 4/3rds sensor.

at a slight tangent, svbony have a rotator that should work in theory though id need m63 down to m54 adapter between focus tube adapter and flattener, then the filter drawer between the flattener and their uncooled 585 camera. whether that all fits im currently trying to work out, plus, my focus tube is at focus about an inch our of the ota which doesn't leave much leeway. there's probably more to it than that but im new to all this so many adapters and sizes and lengths and threads its a bit annoying. luckily im in a good mood as i took 15 x 60 sec subs last night lol. before the clouds came in my guiding was my best ever at 0.82". its annoying seeing it hover under 0.50" for a while before jumping up, but i think that means it has potential, but i won't be sweating over it again if next few sessions it still around 0.8 or 1.0. tilt might be slightly improved but, as i hope to get a cheap astro cam im not gonna sweat that either. i can sweat about any tilt i get once i upgrade camera.

i put the bestest pics of my non premium flattener a few posts above. there is a lighter grey ring of threads in there which i think the filter would go into but i really don't fancy trying to do that in the dark without my sausauge fingers touching the filter glass etc. filter draw and maybe even two filter trays (luxury) seems a better idea for not too much extra cash. if its even possible wiith my gear.

i appreciate what you're saying but i don't trust it all hanging off two screws and i wouldn't even if it was a compression ring type. i have a feeling im also not going to be able to fit a rotator and filter draw into my setup, but im trying to work it out if i can. i 'need' a filter drawer to make reasonably easy access to filter changing, i'd 'like' a rotator. once i can reposition my guider on top of the ota rings (its dew heater band currently gets in the way of the locking bolt for the telescope's dovetail which is annoying) i can rotate the ota in the rings a bit if needed i guess.

Will have a look Ty so much. I'm hoping it's fairly image agnostic so it might do job. I'm thinking two or three panel mosaic on m31 if I get a small sensor, and I bet that's tricky to stick/match

This is great stuff. Sadly the only similar gear I have compared to the gent with his dob is a matching purple top Good luck with your business.

really really nice and love the non red Ha. id love info on a workflow in free software for mosaics, but i'm guessing you use pixinsight?

too small for me to go for but ive seen some really nice images of it.

the weather is terrible. in fact its worse than terrible, its ok enough at times to look promising, only for that promise to disappear as soon as i've set up and polar aligned multiple times. im a master of unlucky imaging ;( with your gear m51 would be my first choice of target. if an image of one galaxy eating another isn't cool, i dunno what is.

sorry for any confusion. i meant in the m57 i took a little while back. i didn't get any of the outer detail, or really even the coloured rings the op did. the pic you showed is the OPs lovely image, not mine. i was just wondering if the OP used starnet++ during his processing, it might be responsible for not being able to see the central star?

Friend is thinking of a s50 for him and his daughters after I've sent him my own (not s50) terrible images over last few months. If after seeing your image he doesn't buy one he's an idiot. He's in bortale9 though,.....

I managed the central star and some central wisps but not galaxy or outer features. I found starnet++ via siril put m57 in the star mask not the starless. Not sure if that relates to bottlestopburley losing the central star?

Wow. Impressive image. Would love to see a Barlow in there. Would also love to see a galaxy or other DSO with this setup

this can't be possible from earth surely? seems it is, somehow
